September and I've only just noticed this thread. "Just one press of the red button ..."
You might still want to make the Distress call - as your set will revert to Ch.16 after the automated alert is sent. This may well reach someone without DSC who may be able to help. Sorry for the delay in responding. J.

I want to warn everyone about a design fault with my Icom M33 (now replaced by a new model). even with the keys locked the on/off button still works. My radio has a tendency to switch itself off if I'm carrying it in a pocket.

Good when I want a peaceful paddle, Bad when the group are trying to contact me.
